PYL1 — Brachypodium distachyon

Summary

BRADI_3G34070V3 (BdPYL1) on chromosome 3 encodes a protein with abscisic acid binding, protein phosphatase inhibitor activity, and kinase regulator activity. It is associated with regulation of abscisic acid mediated signalling, regulation of stomatal opening and movement, release of seed from dormancy, upregulation of seed germination, and activation of defence response to bacteria. The gene has been linked to traits including grain yield, seed yield, vegetative vigor, shoot axis branching, root system architecture, salinity tolerance, osmotic response sensitivity, transpiration rate, and high and low temperature stress response. Studies of related genes in other species connect the family to drought tolerance, ABA signalling, root length, seedling growth, heat tolerance, and virus resistance.
